Cadet is military jargon for a person in officers' training. It is quite misplaced in a civil environment. My point being that far too many FTO's confuse themselves with the Air Force. Also, the organisation PPL/IR shouldn't endorse this confusion, as they are not serving the wannabee ATPL community
Cadet is in common English usage in reference to formal airline training programmes. The article wasn't "endorsing" that. It was using common English.
We must both be having a quiet day to debate a subject of such vital importance....
